I racked a pumpkin brew recently and had a kind of low pH (just over 4.4) It tasted very acidic which I heard is not uncommon for pumpkin ale brews at this stage. However, the beer was very clean and there was no scum ring.

I've been brewing for a few years but have never gotten an infection.

Any advice on other ways to detect infection? Should I just wait a while and see if it comes out okay?
